Designing homes to conserve energy and use it efficiently, from sources that cause least environmental harm.
Some appliances left in standby mode can consume a significant amount of energy.
Many appliances have a standby mode during which they are not providing useful output but still consume energy. Some appliances use standby power to light an LED display while some are waiting for remote control signals to tell them to start operating, or are sending and/or receiving signals to other appliances such as home automation systems.
Standby and baseload consumption together can account for 10% of the energy used in an average house – around $200 per house per year (all electric house @ $0.28/kWh). Baseload consumption is the energy a household consumes under the best possible conditions. For example, it includes a fridge, which is permanently switched on, but not heaters or lights that are only occasionally switched on.
Standby power can be saved by turning appliances off at the wall if they are not being used.
The amount of energy that new appliances use in standby mode has dropped significantly in recent years as they have become more energy efficient.
